Definitions
- This invention relates generally to the field of passenger boarding bridges and more particularly to a method and apparatus for connecting a passenger boarding bridge to a movable body.
- a passenger boarding bridge is used for many purposes, such as connecting a ship or plane to a terminal.
- Many passenger boarding bridges in the shipping industry extend from the terminal and end with a cab near the ship, leaving a small distance between the cab and the ship. In a conventional application, this distance is spanned with a gangplank that engages with both the cab and the ship.
- the cab may be maintained in a fixed position since the bridge is generally connected to a fixed platform, such as a dock, the ship is subject to movement with changing tides. The ship often moves in all three directions--up and down, forward and backward, and from side to side. If the movement is too extreme, the gangway could disengage from the cab or the ship, severing the connection, or alternatively, the ship could collide with the bridge. Either case could result in damage to the ship and bridge or harm to passengers.
- Movement of the ship also affects the inclination of the gangway.
- the inclination of the gangway will change. If ship movement is too extreme, the inclination of the gangway will become unacceptable, requiring adjustment of the cab elevation.
- An apparatus for connecting a passenger boarding bridge to a movable body includes a cab with a periphery on one end of the passenger boarding bridge.
- a gangway connects the cab to the movable body.
- the gangway has a bridge end for engagement with the cab.
- the apparatus further includes an automatic gangway position detection system for sensing the proximity of the bridge end of the gangway to the periphery of the cab.
- an apparatus for connecting a passenger boarding bridge to a movable body includes a cab with a periphery on one end of the passenger boarding bridge.
- a gangway connects the cab to the movable body.
- the gangway has a bridge end for engagement with the cab.
- the apparatus also includes a level sensor positioned on the gangway for detecting the inclination of the gangway and a control system for adjusting the level of the cab responsive to the level sensor.
- a method for connecting a passenger boarding bridge to a movable body having a cab with a periphery includes several steps. Those steps include providing a gangway, between the cab and the movable body, the gangway having a bridge end and a body end. Further steps include engaging the bridge end of the gangway with the cab and engaging the body end of the gangway with the moveable body. Additionally, the proximity of the bridge end of the gangway to the periphery of the cab is automatically detected with an automatic position detection system.
- a technical advantage of the present invention is that a method and apparatus for connecting a passenger boarding bridge to a movable body is provided. Another technical advantage is that the invention provides a method and apparatus for automatically sensing possible disengagement of the connection between the bridge and the movable body. Another technical advantage of the present invention is that it provides a method and apparatus for automatically detecting the possible collision of the ship and the passenger boarding bridge. Another technical advantage is that a method and apparatus is provided for automatically maintaining an acceptable slope between the passenger boarding bridge and the moveable body. Another technical advantage of the invention is that it provides a method and apparatus for automatically alerting passengers and operators of possible disengagement of the connection between the bridge and the moveable body or the possible collision of the movable body with the passenger boarding bridge.
- FIG. 1 illustrates a passenger boarding bridge and the gangway connecting the bridge to a ship.
- FIG. 2A illustrates an enlarged top view of the gangway connecting the bridge to the ship.
- FIG. 2B shows a side view of the gangway shown in FIG. 2A.
- FIGS. 1 through 2B of the drawings like numerals being used for like and corresponding parts of the various drawings.
- a passenger boarding bridge 110 is shown.
- Passenger boarding bridge 110 provides a conduit for passengers to reach a ship 114 from the dock 112.
- the bridge 110 often connects to a ship terminal 113 positioned on the dock 112.
- the bridge 110 includes a passageway 116, which may include multiple nested tunnels 17a, 17b, and 17c.
- the use of multiple tunnels 17a, 17b, and 17c allows for varying the length of the bridge 110 based on width of the dock 112 and distance of the ship 114 from the dock.
- a cab 118 Positioned on the end of the bridge near the ship is a cab 118.
- Cab 118 may be a rotating cab, which allows the cab to be positioned in an orientation approximately perpendicular to the ship. Cab 118 is also positionable to maintain a level orientation parallel to the dock 112 while the bridge 110 may be inclined with respect to the dock 112.
- the gangway has a bridge end 122 that engages with the cab 118 and a moveable body end 124 that engages with the ship 114.
- the bridge end 122 has rollers 202 to allow a movable engagement of the bridge end 112 with the cab 118.
- the moveable body end 124 may be hinged to the ship 114 at the ship departure surface 132 such that gangway 120 remains in contact with the ship departure surface 132, and further connected to the moveable body end 124 in a manner that maintains the gangway 120 in an orientation perpendicular to the ship departure surface 132.
- the bridge 110 is supported by a dock end support 126 and a ship end support 128.
- the bridge 110 may pivot about the dock end support 126. Additionally the ship end support 128 may be on a set of boggies or wheels 130. Thus, through extension of passageway 116, and pivoting about dock end support 126, the bridge may be positioned at any desired point on the dock 112.
- the height of ship end support 128 may be adjustable to vary the elevation of the cab 118 through extension or retraction of hydraulic cylinders in end support 128.
- the height of ship end support 128 may be adjusted manually or automatically through controller 216 (FIG. 2), to which the ship end support 128 is electrically connected.
- FIG. 2A a top view of the cab 118, gangway 120, and ship departure surface 132 is provided.
- Gangway roller 202 is mounted on the lower surface of gangway 120 near the bridge end 122 of the gangway 120.
- an automatic gangway position detection system 203 is provided to detect the presence of the bridge end 122 of the gangway 120 near the periphery of the cab 118 and the possible disengagement of the bridge end 122 from the cab 118.
- the automatic gangway position detection system 203 includes at least one sensor for sensing the position of gangway 120.
- the automatic gangway position detection system includes a plurality of sensors 204 and 208 for sensing the gangway 120.
- Proximity sensors 204 are provided along a portion of the periphery 206 of the cab 118, as shown in FIG. 2A, for detecting the presence of the bridge end 122 of the gangway 120.
- the proximity sensors 204 are positioned near the sides of the cab 118 to detect lateral movement of the gangway 120, which may occur due to movement of the ship 114 in a direction parallel to the dock.
- Proximity sensors 204 may be induction loop detectors. Such detectors are often used in roadways to detect the presence of automobiles near a traffic signal.
- the loop detectors used in one embodiment of the present invention are available commercially from Detector Systems and the model number is 813-103.
- Other types of sensors that can detect the presence of the gangway may be used to sense the gangway along the periphery of the cab near proximity sensors 204, without departing from the scope of the present invention.
- the gangway position detection system 203 may also include a pressure sensitive pad 208.
- Pressure sensitive pad 208 is placed along the cab end 207 for detecting the presence of the bridge end 122 of the gangway 120 near the cab end 207. In the embodiment shown in FIG. 2A, the pressure sensitive pad 208 senses the bridge end 122 by pressure applied by the gangway roller 202. By placing the pressure sensitive pad 208 near the cab end 207, impending disengagement of the gangway 120 from the cab 118 can be predicted and corrective action taken.
- a position sensor such as those described below, may be placed on gangway 120 near roller 202 to detect the proximity of a portion of the cab end 207, and therefore the impending disengagement of the gangway 120 from the cab 118.
- Pressure sensitive pad 208 may also be placed along the remainder of the periphery 206 of the cab 118, as part of the automatic gangway position detection system 203, to detect the presence of the bridge end 122 of the gangway 120 near the periphery 206.
- a cab position sensor 210 Placed on the gangway is a cab position sensor 210.
- Cab position sensor 210 detects the presence of the cab 118 and thus provides an indication of the distance between the ship 114 and the cab 118. As the ship 114 drifts toward the cab 118, gangway 120 rolls on rollers 202 toward the bridge 110. Since cab position sensor 210 is fixed on gangway 120, cab position sensor 210 may provide an indication of the proximity of the ship 114 to the cab 118.
- Cab position sensor 210 may be any type of sensor that may detect the presence of an object, including a simple switch mounted on the gangway for engagement with the cab 118.
- the cab position sensor 210 may be a photoelectric sensor. Such a position sensor is available commercially from Cutler-Hammer and the model number is 13104A6517.
- a level sensor 212 is mounted on the gangway 120 for detecting the inclination angle 214 (FIG. 2B)of the gangway 120. Since the ship 114 may rise or fall and drift toward or away from the cab 118, inclination angle 214 will vary.
- the level sensor 212 may be a pendulum-type level sensor, inclinometer, or any other type capable of producing an electronic signal responsive to changes in the inclination angle 214.
- One type of level sensor appropriate for use in the invention is available from PQ Controls (Model Number 410).
- Level sensor 212 is connected to a controller 216 for raising or lowering the cab 118 when inclination angle 214 exceeds a predetermined limit.
- the desired inclination angle is between zero and four degrees, with two degrees serving as a desired angle.
- the automatic gangway position detection system 203 and the cab position sensor 210 are also connected to a controller 216, which is programmed to actuate an alarm 218 in response to detection by these sensors.
- the controller 216 also may be programmed to prevent the actuation of an alarm, for example during maintenance or repair of the gangway.
- the controller 216 could automatically adjust the cab 118 in response to detection of movement of ship 114 by automatic gangway position detection system 203 and the cab position sensor 210, historical data indicates the predominate ship movement is in the vertical direction. Therefore, in one embodiment, the position of the cab 118 is adjusted manually in response to indications from the gangway position detection system 203 and the cab position sensor 210, leaving automatic adjustment of only the elevation of cab 118 to the controller 216.
- the automatic position detection system 203 and cab position sensor 210 may be coupled to an alarm, either directly or through controller 216, for providing a warning to passengers and operators that the gangway 120 is nearing the periphery 206 of the cab 118 or that the ship is too close to the cab 118. In response to this warning an operator can adjust the cab position 118 through extension or retraction of passageway 116 or relocation of the ship end support 128 along the dock 112.
- the alarm 218 may be audible, visual, vibratory, or a variety of well known types of alarms.
- the cab 118 is positioned close enough to the ship 114 so that the gangway may be hooked on to the ship departure surface 132 and positioned such that the bridge end 122 of the gangway may be located approximately midway between the two proximity sensors 204 located on opposite ends of the cab 114 along the periphery 206. In one embodiment, the cab 118 is then backed away approximately three feet from the ship 114, which provides a safe distance for varying movement of the ship.
- the gangway will roll along the cab until the cab position sensor detects the cab 118.
- an alarm 218 may be triggered, alerting an operator to back the cab 118 away from the ship 114 a safe distance.
- the gangway will also roll parallel to the dock 112. If the ships drifts enough, the bridge end 122 of the gangway will contact the periphery 206 of the cab 118 above the proximity sensor 204. Proximity sensor 204 will detect the presence of the bridge end 122 of the gangway 120. The proximity sensor 204 may trigger an alarm 218, alerting an operator to reposition the cab 118 so that the bridge end 122 of the gangway is located approximately midway between the proximity sensors 204 on opposite ends of the cab 114 along the periphery 206.
- the gangway will roll along the cab 118 until the pressure sensitive pad detects the gangway roller 202.
- an alarm 218 may be triggered, alerting an operator to position cab 118 closer to the ship 114.
- the inclination angle 214 of the gangway 120 will vary. This angle is measured by the level sensor 212. If the inclination angle exceeds a predetermined angle, a controller 216 will be activated to adjust the elevation of cab 118 through raising or lowering ship end support 128 so that it is closer to the elevation of the ship departure surface 132.
- the predetermined angle is zero to positive four degrees, with positive two degrees a desired set point. In the same embodiment, when the inclination angle exceeds positive four degrees, which corresponds to an upward slope of the gangway, such as that shown in FIG.
- the level sensor 212 sends a signal to the controller.
- the controller adjusts the level of the cab (in this case raising it upward)until the inclination angle is approximately three degrees, at which point the signal from the level sensor is terminated.
- the controller 216 may also continue to reposition the cab 118 for a predetermined time period to further reduce inclination angle 214, thereby reducing cycling of the elevation of cab 118.
- a time delay of approximately two seconds after termination of the signal from the level sensor further reduces the inclination angle from 3 degrees to 1 degrees, which overcorrects the inclination angle 214 past the desired set point of two degrees to reduce cycling.
- a delay may also be placed into the controller 216 so that the elevation of cab 118 is not changed in response to transient disturbances, such as waves.
- the controller 216 delays adjusting the cab 118 elevation approximately ten seconds.
